Answer:

C) 12

Step-by-step explanation:

Consecutive interior angles are supplementary:

(9x -4)° +(5x +16)° = 180°

14x = 168 . . . . . . divide by °, subtract 12

x = 12 . . . . . . . . divide by 14

I have to find the angle measurements of a interior triangle a is 4x b is 7x-2 and c is 5x-10

RSB [31]

Answer:

$m\angle a=48^o\\m\angle b=82^o\\m\angle c=50^o$

Step-by-step explanation:

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

$m\angle a+m\angle b+m\angle c=180^o$

substitute the given values

$4x^o+(7x-2)^o+(5x-10)^o=180^o$

solve for x

$(16x-12)^o=180^o$

$16x=180+12\\16x=192\\x=12$

Find the angle measurements

$m\angle a=4(12)=48^o$

$m\angle b=7(12)-2=82^o$

$m\angle c=5(12)-10)=50^o$

Ryan earns $5 for each small dog he walks and $8 for each large dog he walks. Today he walked 9 dogs and made a total of $51. Ho

Shalnov [3]

Use a system of equations.

(x=# of small dogs, y=# of big dogs)

x+y=9 (times by -5) -5x-5y=-45
5x+8y=51

Then add the equations together and the x's cancel.

3y=6
y=2

So he walked 2 big dogs and 7 little dogs.

A car rental company offers two plans for renting a car. Plan A: $30 per day and 18 cents per mile Plan B: $66 per day with free

Alisiya [41]

Answer:

200 miles

Step-by-step explanation:

Set up a cost equation for each plan using x for miles.

Set the equations equal.

Solve for x, the miles.

For a 1 day rental.

Plan A:

C = 0.18x + 30

Plan B:

C = 66

0.18x + 30 = 66

0.18x = 36

x = 36/0.18

x = 200

Answer: 200 miles
